Over the weekend, the Pope wrote in an email to Argentine lawmaker and friend Gustavo Vera, “Hopefully we are in time to avoid Mexicanization,” referring to the country’s drug trade, the Associated Press reports. After Vera published the email on the website for his organization, the Alameda Foundation, Mexico formally complained that the Pope was unnecessarily “stigmatizing Mexico” despite the country’s efforts to battle drug cartels there.

In response, the Vatican sent Mexico’s ambassador an official note and said the Pope’s choice of words were taken from a informal, private email that merely borrowed language Vera himself had used as lawmaker battling Argentina’s own drug trade.

“The Pope intended only to emphasize the seriousness of the phenomenon of the drug trafficking that afflicts Mexico and other countries in Latin America,” Vatican spokesperson Rev. Federico Lombardi said. “It is precisely this importance that has made the fight against drug trafficking a priority for the government.”
